Product details
Overview
SA6.0AHE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor diode in DO-15 package, rated for 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 500 W peak pulse power (10/1000 μs), and AEC-Q101 qualified for automotive applications. It protects MOSFETs and ICs against inductive switching transients in power supply rails.
For engineers reviewing the SA6.0AHE3/54 datasheet, SA6.0AHE3/54 pinout, SA6.0AHE3/54 application, or SA6.0AHE3/54 equivalent, key selection criteria include clamping voltage (48.5 V at 600 A), low incremental surge resistance, fast response time, and RoHS-compliant AEC-Q101 qualification for under-hood electronics.
Technical Context
The SA6.0AHE3/54 operates as a unidirectional avalanche diode with glass-passivated junction, designed to clamp transient overvoltages before they damage downstream circuitry. Its 10/1000 μs waveform rating supports repetitive surge events at 0.01% duty cycle, and it exhibits 10.3 V maximum clamping voltage at 600 A IPPM.
Thermal performance is defined by a 175 °C maximum junction temperature and 3.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C. The device features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets JESD 201 Class 2 whisker test requirements due to the HE3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum reverse working voltage before conduction begins; defines safe operating margin for 5 V rail protection. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed avalanche onset range; ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 48.5 V at 600 A - Clamped voltage during worst-case 10/1000 μs surge; determines protected circuit's maximum stress level. |
| PPPM | 500 W - Peak pulse power handling per single 10/1000 μs event; enables robust protection against load dump and inductive kick. |
| ID @ VWM | 600 μA - Reverse leakage at rated stand-off; low enough to avoid interference in high-impedance sensor or bias networks. |
| TJ max. | 175 °C - Maximum junction temperature; supports operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
SA6.0AHE3/54 uses the DO-15 (DO-204AC) axial-leaded package: molded epoxy body, 0.130–0.138 inch diameter, 1.0 inch minimum lead length, matte tin-plated leads. Polarity is marked with a cathode band on the case end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry (unidirectional mode) | Connected to ground or low-side return path; conducts during forward surge events (e.g., reverse battery protection). |
| Cathode | Reverse-biased terminal during normal operation | Connected to protected line (e.g., 5 V rail); avalanches into conduction when Vline exceeds VBR, shunting surge to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress. |
| 500 W peak pulse power (10/1000 μs) | Supports high-energy transients such as ISO 7637-2 Pulse 5a (load dump) without degradation. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain and body electronics where failure modes are safety-critical. |
| Low clamping ratio (VC/VBR ≈ 6.6) | Minimizes voltage overshoot during clamping-critical for protecting 5 V logic interfaces and microcontrollers. |
| RoHS-compliant HE3 suffix | Indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance-required for automotive production traceability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/52 | Same VWM (6.0 V), same DO-214AC package, but lower PPPM (400 W) and higher VC (52.3 V at 59.3 A). | Less suitable for high-current load dump; better for space-constrained PCBs where SMD is preferred over axial DO-15. | Select SMAJ6.0A-E3/52 only if board layout mandates SMD and surge energy is limited to ≤400 W. |
| P6KE6.8A | Higher VWM (6.8 V), same DO-15 package, 600 W PPPM, but not AEC-Q101 qualified and higher VC (11.2 V at 53.3 A). | Lacks automotive qualification; acceptable for industrial/commercial use where reliability validation is less stringent. | Choose P6KE6.8A only for non-automotive designs requiring slightly higher standoff and no AEC-Q101 requirement. |
Compared with SMAJ6.0A-E3/52 and P6KE6.8A, SA6.0AHE3/54 uniquely combines AEC-Q101 qualification, 500 W pulse rating, and 48.5 V clamping in DO-15-making it the only option validated for automotive under-hood deployment with tight voltage margins.

FAQ
What is the clamping voltage of SA6.0AHE3/54 and how is it measured?
The SA6.0AHE3/54 has a maximum clamping voltage (VC) of 48.5 V at 600 A peak pulse current, tested with a 10/1000 μs waveform per IEC 61000-4-5. This value represents the actual voltage seen by protected circuitry during worst-case surge events and is confirmed in Vishay's datasheet revision 27-Sep-2021, page 2. The SA6.0AHE3/54 maintains this clamping performance across its qualified temperature range.
Is SA6.0AHE3/54 suitable for automotive applications?
Yes, SA6.0AHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, JESD 201 Class 2 whisker resistance, and DO-15 mechanical robustness meet automotive reliability standards. The SA6.0AHE3/54 is commonly deployed in engine control modules and body electronics for load dump and ESD protection.
What does the "HE3" suffix mean in SA6.0AHE3/54?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. Unlike the commercial "E3" variant, HE3 confirms full automotive-grade process validation, including extended temperature cycling and high-temperature reverse bias testing. This makes SA6.0AHE3/54 distinct from non-HE3 variants in reliability-critical deployments.
How does SA6.0AHE3/54 differ from bidirectional TVS diodes like SA6.0CA?
SA6.0AHE3/54 is unidirectional and features a cathode band for polarity identification; it conducts in forward bias and clamps reverse transients. In contrast, SA6.0CA is bidirectional with no polarity marking and clamps both positive and negative surges symmetrically. SA6.0AHE3/54 offers lower leakage and tighter VBR tolerance than SA6.0CA, making it preferable for DC rail protection where polarity is fixed.
Can SA6.0AHE3/54 be used in place of SA5.0AHE3/54?
No-SA6.0AHE3/54 has a 6.0 V stand-off voltage versus SA5.0AHE3/54's 5.0 V, resulting in different clamping thresholds and compatibility with 5 V vs. 3.3 V systems. Substituting SA6.0AHE3/54 for SA5.0AHE3/54 risks insufficient protection margin on 3.3 V rails or premature conduction on 5 V rails. Always match VWM to the protected rail's nominal voltage; SA6.0AHE3/54 is intended for 5 V systems with headroom.
